The cameras were still rolling when Jon Boast looked into the lens from his hospital bed and told viewers what his doctors had just confirmed. “The blood test results suggest that I’ve had a mild heart attack.” He said it plainly, as if reporting it rather than living through it.
Boast is the husband of A Place in the Sun presenter Jasmine Harman and, by profession, a television cameraman. He has spent two decades behind the lens on other people’s stories. In 2025, he became the subject of one.
What that Channel 4 episode captured was the third health crisis he had faced that year. Before the heart attack, there had been a broken leg. Before the leg had healed, a blood clot developed. The full scale of Jon Boast’s illness only became clear when all three events were placed side by side.

Jon Boast’s 2025 Health Timeline: Broken Leg, Blood Clot, Heart Attack

By the time Jon’s chest tightened in May, Jasmine was already aware he was carrying a blood clot from the earlier fracture. That fact sat in the room when she called the ambulance.
What Happened the Day of the Heart Attack in Estepona
Jon Boast was 45 years old when it happened. He had been at the couple’s unfinished villa in Estepona, on Spain’s Costa del Sol, talking to one of the builders working on the renovation. The chest tightness came on suddenly, followed by aching in both arms. He went inside to rest. The symptoms did not settle.
Jasmine recalled the moment in her exclusive interview with The Mirror:
“We’d just had lunch and he said he started to feel funny and strange. He went to lie down but he then started to get very agitated and said there was a tightening in his chest.”
He was struggling to breathe and everything touching him was causing irritation. Jasmine called an ambulance straight away. Despite knowing about the existing blood clot, she kept her composure:
“As he had thrombosis from the leg break, it was obviously scary but I don’t know why, something inside me was saying: don’t panic, it’s going to be fine. I was very calm.”
At the hospital in Estepona, blood tests confirmed the diagnosis. Jon addressed the cameras directly from his bed:
“Just when we thought we were getting back to normal life, mid-renovation, this afternoon when we were with one of the builders, I got sort of pains in my chest and tight chested, achy arms. We called an ambulance and now I’m in hospital. The blood test results suggest that I’ve had a mild heart attack.”
He added: “I think sometimes it’s called angina, which sounds way less scary than a heart attack, but anyway, they’re doing tests.”
Earlier in that same episode, Jon had spoken on camera about his family’s cardiac history. Hours later, he was in a hospital bed. Most viewers watching on 11 November 2025 would not have registered the connection until it was unavoidable.
The Family Cardiac History Behind Jon Boast’s Illness
The heart attack did not come without context. Jon’s sister, Jo Boast, died suddenly in 2016 at the age of 40 from sudden arrhythmic death syndrome, a condition known as SADS. Jasmine said of the loss: “She was fit, well and very healthy. It was a very big shock.”
SADS and a heart attack are two entirely separate cardiac events:
- A heart attack occurs when blood flow to the heart is blocked, typically confirmed through blood tests showing damage to the cardiac muscle — as happened with Jon in May 2025
- Sudden arrhythmic death syndrome (SADS) is diagnosed when someone dies from cardiac arrest with no structural cause found at post-mortem. The heart looks completely normal. The problem lies in the heart’s electrical rhythm, not its arteries
According to the British Heart Foundation, SADS accounts for around 500 deaths per year in England — eight times higher than earlier estimates had suggested. Families carry a significantly elevated risk when the condition has already appeared in a first-degree relative.
Research shows that over half of families affected by a SADS death carry some form of inherited cardiac condition. Early screening can lead directly to preventive intervention.
Why Jon Was Already Being Screened — and Why That Mattered
Jo’s death in 2016 pushed Jon to take his cardiac health seriously in a way that proved consequential. He began attending regular cardiac screenings specifically because of what had happened to his sister.
When he arrived at the Estepona hospital in May 2025, that screening record was part of the clinical picture doctors were working from. Jasmine confirmed this:
“With Jon’s family history, he’d already been having regular screenings. Now they are doing more investigations and keeping an eye on him. He’s on medication and they will continue to do regular monitoring.”
The interior design company My Bespoke Room, which worked on Renovation in the Sun, later confirmed publicly that Jon had been unwell twice during filming and that the full weight of the project had fallen on Jasmine throughout. Her mother, Vasoulla, flew from the UK to Spain during the hardest stretch.
Jasmine said: “With Jon also breaking his leg, now when I look back on everything, I don’t know how I did it. What I do know is I wouldn’t have been able to do it without my mum. When she arrived, I let go of all the pressure and the stress.”
Jon Boast’s Recovery and Current Health
As of late 2025, Jon Boast had recovered fully and returned to work. The Estepona home was finished. Jasmine confirmed his recovery in her Mirror interview, published the week the episode aired — four days before she turned 50 on 15 November:
“Jon is fine now and he is back working. I know this sounds strange but even with the background of what could have happened and worrying he could have died, it makes you feel lucky he just had a mild heart attack and everything is fine.”
He remains on medication with ongoing cardiac monitoring in place.
The Full Weight of What This Couple Had Already Been Through
Jon’s health problems in 2025 were the latest chapter in several years of significant loss for him and Jasmine.
- 2016 — Jo Boast died suddenly at 40 from SADS
- 2017 — A pregnancy through IVF ended when the embryo failed to implant
- February 2024 — Jasmine lost her close friend and A Place in the Sun co-presenter Jonnie Irwin to lung cancer, aged 50
- 2025 — Jon’s broken leg, blood clot and heart attack, all within five months
Jasmine spoke about what this accumulation had done to her outlook:
“The challenges life throws at you has made me take things in my stride a lot better than I used to. I used to be quite a control freak but now I feel I am able to go much more with the flow and not let things get under my skin.”
Jon Boast has spent his career framing other people’s moments for television. The footage from that May afternoon in Estepona, broadcast to Channel 4 viewers six months later, was the closest he has ever come to being the story himself.
When asked about the completed home, he told Hello! magazine: “Stepping through this door is like a sigh of relief. This is not just a house, it’s our sanctuary.”
After everything 2025 brought, that is not a small thing to be able to say.
